Surface Properties from N-Views of a Strictly Convex Solid

This paper shows that a strictly convex solid under observation by two or more cameras with known extrinsic and intrinsic parameters contains points on its surface calculable in terms of multiple photographic images. In the case of a solid with a C-1 boundary we can also extract surface orientation at these points, and when the solid has a C-2 boundary and a known reflectance map, curvature information can also be calculated.
